Probably blink would be nicer and exit the "99% useless"... ehm I mean "niche"
category if it was somewhat regulated. Like, if it
always brings a mage "to a location without a single opponent within 3 squares", it could be still niche but good for casters (communion slaves i.e., but even battlefield enchantment casters) to delay the moment they will get caught by the enemy flankers if they manage to pass through the "blockers".
